In-depth analysis of Nginx cross-origin AJAX requests, nginxajax

Cross-origin occurs when AJAX requests from one domain to another. So how can I implement ajax cross-origin requests on nginx? To enable cross-origin requests on nginx, add the add_header Access-Control * command. As follows:

Location/{add_header 'access-Control-Allow-origin' 'HTTP: // other.subdomain.com '; add_header 'access-Control-Allow-Credentials' 'true '; add_header 'access-Control-Allow-Methods ''' GET ';...... the rest of your configuration here ......}

Note:

First Command: authorize requests from other.subdomain.com

Second command: when the flag is true, the response is to whether the request can be exposed.

The third day command: Specifies the request method, which can be GET or POST.

If you want to allow access from any domain, you can configure it as follows:

Access-Control-Allow-Origin :*

Restart nginx

Service nginx reload

Ajax cross-origin request test

When the request is successful, the response header is as follows:

HTTP/1.1 200 OKServer: nginxAccess-Control-Allow-Origin: other.subdomain.com
